On This Day In History
March 3rd, 1917: Egyptian nuclear physics Sameera Moussa was born. She was an activist for peaceful uses of nuclear energy, especially as a form of cancer treatment. She was the first woman to work at Cairo University and the first person of color to be allowed to visit secret US atomic facilities—a highly controversial event.

About Nucear Permanent Disposal Sites
Tumblr media
So, a couple of days ago someone commented under my one blog about nuclear energy what boiled down to: "But what about the waste? We need to take responsibility for the next thousands of years of humanity!" And yes, that is very much the favorite argument for the anti-nuclear lobby... and it is pretty much based on the science of the 1980s.
What a lot of people do not understand is:
How little nuclear waste we actually have.
How little of that waste is actually the highly radiating stuff.
How well we can contain this stuff.
That we actually have figured out a solution for permanent disposal.
Tumblr media
First need about nuclear waste you have to understand that most of it is not that dangerous. Most of the waste we get out of the nuclear facilities is actually just stuff that was around the radiation and got slightly radiated. 90% of all nuclear waste is stuff like items that just happened to be within the nuclear facilities for a long while. Tools, wortk clothing and so on. This stuff radiates, yes, but it is technically not dangerous levels AND it will stop doing so within 100 years max. We literally do not need to worry about it. Those yellow barrels you will keep seeing in old media that somehow end up mutating people? Yeah, those are used for this kind of waste. And to be quite frank, we are super extra that we store this either way. Because we have waste from other types of facilities (like coal power, but also from places like airport) where this kinda waste also happens and we... just throw it away normally.
Then there is about 7% of nuclear waste that is a bit more radiated. This is mostly metal parts and such that were in direct contact with the nuclear elements. This gets more radiated and as such will radiate for a longer time. But, this, too, is radation that will be gone or down to safe levels within a few centuries.
Only 3% is waste, that is high-level radiating and even from this not all will radiate for millennia! In fact we have gotten real good with recycling this high-level waste and if we are now talking SciFi scenarios like Solarpunk, we could actually just switch to thorium based reactors, where almost all of it is recyclable.
But... Even with the high level radiating stuff that we cannot recycle and need to permanently store, we... actually long have a solution for it.
Tumblr media
You have to realize that those fuel cells are actually pretty small. And that we have materials that can basically protect you from the radiation. So, we basically just take those small spend fuel cells, put them into glass, put that into several layers of metal, put all of that into a deep, deep hole the ground and then fill everything up with clay. And... done.
Chances are: Nobody is gonna find it. Because it is gonna be so deep underground. Even if they did: It is protected enough that nobody is gonna die of radiation poisoning directly. Not only that: But the best rock material to burry this stuff in, is already radiating. So... Like, duh. We already have super radiactive stuff in nature.
And even if someone got radiation poisoning... Unless you suppose that humans of the future are dumber than most animals... They will learn: "Dude died. Area bad. Do not dig there."
Scientifically speaking... The entire nuclear waste thing is such a fucking non-issue, that keeps getting pushed up mostly by fossil fuels (that, again, also produce radiating waste!) to keep folks from going for a full renewable + nuclear energy mix. Aka: The clean option.
The reason why so many politicians do not just agree to those disposal options is that a) they do not understand it themselves and b) nor do their constituents and there is sooooo much fearmongering about this going on.
Again, I am not saying that we should go full nuclear energy. But rather for an energy mix of renewables and nuclear. Be CO2 neutral. Because I can tell you one thing: If we do not do that, there are not gonna be humans in 3023 we have to worry about. Because they are all fucking dead, with the planet being inhospitable to life.

SaskPower and GE Hitachi have signed an agreement to advance the development of nuclear power in Saskatchewan.
The agreement, signed Tuesday morning at SaskPower headquarters in Regina, is part of a plan to develop a small modular reactor (SMR) in the province.
SaskPower says it will work with GE Hitachi on design, fuel sourcing and fabrication for a BWRX-300 reactor, the technology selected in 2022.

i learned that the radiation in a nuclear power plant doesn’t produce electricity. It heats water into steam which runs a turbine that creates electricity (x)

Probably, there are the largest number of rumors and myths about nuclear energy, so I decided to analyze this topic.
I believe that the Chernobl and Fukushima accidents, as well as the nuclear weapons situation from the 1950s to the 1990s, gave nuclear power a bad name. But now, nuclear energy is one of the most efficient and safest in the world.
First, we need to understand how nuclear editors work. Due to the decay of uranium, a large amount of heat is created, which heats the water, and the steam spins the blades, generating electricity. Further, the steam turns into an aqueous state, is purified and clean water enters the tank. Many people may think that a nuclear power plant consumes water, but no, the water after treatment becomes very clean, so it harms aquatic inhabitants. Therefore, nuclear power plants do not harm the environment, unlike coal.
You can say that the stations are exploding and it's extremely dangerous. But now the chance of an explosion of the nuclear power plant is minimal, because people have been studying each accident closely, drawing conclusions and improving the construction technique. Here the situation can be compared to airplanes, because airplanes used to be an extremely unreliable way of transportation, but people, improving their technique of aircraft construction, have achieved that now the airplane is the safest transportYou can say that the stations are exploding and it's extremely dangerous.

Based on this, I conclude that nuclear energy is now one of the safest, cheapest and most environmentally friendly in the world, and there is definitely no need to be afraid of it.
As always, you can express your point of view in the comments.

This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long.
These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion.
And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender!
NASA and the Soviet space program spent decades researching nuclear propulsion during the Space Race.
A few years ago, NASA reignited its nuclear program for the purpose of developing bimodal nuclear propulsion – a two-part system consisting of an NTP and NEP element – that could enable transits to Mars in 100 days.

Would Nuclear Energy ever be part of a Solarpunk society? Or rather, do you think that Nuclear Energy could ever be used in a Solarpunk society, without breaching into Atompunk?
Thank you for the question.
Now, let me prephase this with saying, that I am very pro-nuclear, due to my degree and due to having done an internship in a nuclear power plant 12 years ago. I think that the fear of nuclear desaster is greatly overblown, mostly because the worst case scenario is so scary, no matter how rare it is. Which is why many will prefer coal to nuclear, even though the scenario in which coal operates as intended is just as scary. But in a way that we have gotten used to.
However, there is the fact that for the construction of a nuclear power plant we need a lot of steel and concrete, two things that we currently cannot produce without emitting a lot of CO2. While most renewables also need both things, the amount needed is a lot less, even based on the amount of energy generation.
And, admittedly, there is also currently the issue of how the nuclear fuels are mined in often unsafe conditions for the workers and the environment and in some cases on indigenous land without the consent of the indigenous people in question and without them being compensated for it. Though other than the CO2 issue, those things could be regulated for better outcomes.
Even though, I do think that the quickest way to shift to entirely green energy would be to supplement a renewable grid with nuclear reactors. Ideally new nuclear reactors that meet modern safety standards. While nuclear is still always fairly safe, it is unconscionable that a lot of the reactors in use right now were once built for a twenty year useframe and are now at times going on to thirty or forty years.
The reason I am for an energy mix that includes nuclear is, that we right now have an issue with storing renewable energy. While this is a much smaller problem then fossile fuel cronies will make it out to be, we still do not have a reliable method to store large amounts of energy outside of using hydropower. Which means, that we do need a way to supplement renewable energies for those days when renewables do not create enough energy. Especially until we have build better energy grids. And I think that nuclear is good for that.
So, yes, I do think that nuclear has its place within Solarpunk, just not as a main energy source and rather a supplemental source of energy to help us shift.
Going into 70-80% nuclear instead of renewables (like France is doing) would be a mistake. But a 20-30% nuclear with 70-80% renewables energy mix should be a good solution.
Because I can guarantee you one thing: Nuclear is definitely safer than fossil fuels - even ignoring the entire climate change issue.
I hope that answers the question.
